Skin and scalp experts say there are different causes of dandruff, and not everyone can get rid of it with regular shampoos.
Dandruff is a non-inflammatory skin condition that causes scalp flaking, according to the National Institutes of Health.
“While the winter months can lead to dry scalps, the term ‘summer dandruff’ also exists because sweat, dirt, humidity, pool chemicals, and sun exposure can also trigger dandruff,” Alexia Donovan, director of client services. in the Barber Surgeons Guild, he told Fox News.
“Several factors can contribute to dandruff: dry skin, psoriasis, oily scalp, and fungus are the most common causes,” she elaborates.
Research has shown that dandruff affects about 50% of people at one point or another in their lives, for her part, trichologist Celestine Guetou, hair research specialist.
“It manifests itself through scales on the scalp. The scales are white or yellow in color,” she explains.
Dandruff is usually caused by colonization of the skin by a yeast called Malassezia globosa, reports the New York Post.
“Malassezia globulus feeds on sebum and breaks it down into oleic acid. The presence of oleic acid in some people causes itching and irritation of the scalp,” explains Ms. Gitto.
Here are 4 tips to get rid of dandruff.
1. Special shampoos
To fight persistent dandruff, Donovan recommends shampoos containing zinc, selenium sulfide, or ketoconazole, all of which are added to most dandruff shampoos.
“If your dandruff is chronic and not improving, a hairdresser or dermatologist should be consulted, as a prescription medication may be necessary,” says Donovan.
Dandruff can be treated when the scalp is cleaned and moisturized regularly, says Dr. Mariano Bosso, MD, a board-certified dermatologist who practices in Florida and California.
For flaky scalps, dandruff sufferers recommend using a “mild shampoo” specifically designed to remove dandruff.
These specialized shampoos usually contain antifungal ingredients, including zinc pyrithione, ketoconazole, and selenium sulfide.
“Adding an antifungal shampoo to your routine will help fight dandruff caused by an overgrowth of yeast,” Bosso told Fox News.
He adds that it is important to rinse the scalp and hair thoroughly to ensure there is no residue upon washing.
2. Daily brushing
Ms. Donovan also suggests brushing the hair and scalp daily to reduce the buildup of oil and dead skin between washes.
For people with mild dandruff that doesn’t require medical intervention, she recommends washing hair with a “good quality mild shampoo” when it comes to removing heavy styling products.
3. Avoid sunburn
People whose scalps are exposed to the sun should consider wearing a hat to prevent sunburn on the scalp, according to Donovan.
The scaling that occurs with a burned scalp often looks like dandruff.
4. Beware of heating tools
Mr Bosso warned that people with dandruff should also be careful when styling and drying their hair after washing it.
“The use of heat tools and styling products should be kept to a minimum, as they can exacerbate dandruff,” he warns.
